Title: Production of horseshoe crab amebocytes in vitro
Inventor: GIBSON DANIEL G III
IPC: C12N5/07
Filed: 1989-12-27
Granted: 1995-07-18
Abstract: A method for producing horseshoe crab amebocytes in vitro by isolating amebocyte producing tissue from the gill flaps of horseshoe crabs, especially Limulus polyphemus.  In contrast to all previous attempts to isolate and culture amebocytes from Limulus for the production of pyrogen-sensitive lysate, an effective method and means has been developed utilizing the discovery that the gill flaps are the source of the cells which differentiate into competent amebocytes. Once isolated, the tissue can be cultured long term in vitro on an artificial surface or as part of the gill flap leaflets, opened along one edge to allow access of the media to the developing amebocytes. Amebocytes are removed from the gill flaps by pulsing with Limulus serum, copper sulfate, detergent, or combinations thereof.

Title: Secure integrated circuit chip with conductive shield
Inventor: GILBERG ROBERT C
IPC: H01L29/792
Filed: 1990-01-10
Granted: 1994-08-16
Abstract: An integrated circuit chip containing a secure area in which secure data is processed and/or stored, includes a semiconductive layer containing diffusions defining circuit element components; a first conductive layer coupled to the semiconductive layer to interconnect the components to thereby define circuit elements for distributing, storing processing and/or affecting the processing ofsecure data; and a second conductive layer overlying the circuit elements to thereby define a secure area in which the circuit elements are shielded from inspection, and coupled to the circuit elements for conducting to the circuit elements a predetermined signal that is essential to an intended function of theshielded circuit elements, whereby removal of the second conductive layer will prevent the predetermined essential signal from being provided to the circuit elements and thereby prevent the intended function.
Patent CA-2012488-C (CA)
Inventor: VAN ERDEN DONALD L
IPC: A44B19/16
Filed: 1990-03-19
Granted: 1999-05-25
Abstract: A flexible continuous reclosable plastic zipper having one strip with a groove and another strip with a rib for interlocking insertion therein, a hot melt plastic peel seal in the base of the groove with the rib bonded to the peel seal material to initially join the rib and groove and with the rib and groove breaking apart away from the bonding material at the first opening and thereafter releasably interlocking in a normal manner with the peel seal material remaining within the groove.  The groove is made sufficiently deep so that with initial interlocking, the rib must penetrate to the base of the groove deeper than normal operation to lock to the peel seal. When broken from the peel seal, the rib inserts sufficiently for the jaws of the groove to snap over the rib and then locks without interference from the peel seal which is relatively rigid and nonadhesive after the rib is first broken away.

Title: Dynamic shared facility system for private networks
Inventor: GORDON TRAVIS H
IPC: H04M3/00
Filed: 1990-04-11
Granted: 1993-11-09
Abstract: DYNAMIC SHARED FACILITY SYSTEM FOR PRIVATE NETWORKS Abstract This invention relates to a dynamically shared facility network (DSFN) providing private network service to a plurality of customers using switched facilities of a common carrier network. A plurality of serving offices are connected via access links to customer telecommunications equipment. A pool of channels is dedicated to providing communications for private network service among these serving offices. In response to a request from a customer, connections are set up in the serving offices between access links and members of the pool of channels, in order to interconnect the serving links sought to beconnected by the request. Where tandem connections between serving offices are necessary, connections are set up between members of the pool of channels. In case of failure of one or more channels, a new connection is automatically established. Advantageously, communication channels of the large communications facilities of a public switched network can be allocated to the DSFN, thus achieving economies of scale, and thus permitting use of the large and flexible switching systems of the public switched network to control and switch channels of the DSFN.

Title: Mixing apparatus and method
Inventor: ALLEN THOMAS E
IPC: E21B33/13
Filed: 1990-09-20
Granted: 1995-11-07
Abstract: A mixing apparatus comprises two or more tubs in which mix-tures can be mixed to obtain averaging of a particular property, such as density.  Two recirculation lines are used.  One recir-culates between an initial mixing tub and a mixing inlet, and the other recirculates from the additional, secondary averaging tub(s) and the mixing inlet.  Computer control responds to den-sities of fluids recirculated through both of the recirculation lines.  In a preferred embodiment, the computer is also respon-sive to pressure of one of the inlet substances.  In response to these measured inputs and other data entered through a data entry terminal, the computer generates control signals for controlling the inputs of both of two inlet substances.  In a preferred embo-diment, the apparatus and a corresponding method utilize displa-cement tanks both as averaging tubs and as conventional displace-ment tanks.

Title: Machine method of balancing credit and debit transactions
Inventor: DUFFIELD DANIEL A
IPC: G06Q40/00
Filed: 1990-09-26
Granted: 1994-08-23
Abstract: A method of assisting an operator in balancing large transactions with subtotals as occurs in the banking industry.  A typical deposit for a bank may include several bundles of checks, with each bundle being wrapped in an adding machine tape which has thereon a total monetary amount for the checks included in that bundle, and it also includes a deposit slip which includes a grand total of the monetary amounts of all the groups of checks associated with the deposit slip.  Balancing such a large transaction is performed on a bank proofing machine.  A Proof Total (associated with the grand total) and a Subtransaction Total (associated with each group of documents being run) are maintained to assist an operator in finding an error when one does occur.  The current "adding machine mode" of balancing is discussed for comparison with the method of this invention.

Title: Computer neural network supervisory process control system and method
Inventor: SKEIRIK RICHARD D
IPC: G05B13/02
Filed: 1991-07-25
Granted: 2002-02-26
Abstract: A neural network for adjusting a setpoint in process control replaces a human operator. The neural network operates in three modes: training, operation, and retraining. In operation, the neu-ral network is trained using training input data along with input data. The input data is from the sensor(s) monitoring the process.      The input data is used by the neural network to develop output data. The training input data are the setpoint adjustments made by a human operator. The output data is compared with the train-ing input data to produce error data, which is used to adjust the. weights of the neural network so as to train it. After training has been completed, the neural network enters the operation mode. In this mode, the present invention uses the input data to predict out-put data used to adjust the setpoint supplied to the regulatory con-troller. Thus, the operator is effectively replaced. The present in-vention in the retraining mode utilizes new training input data to retrain the neural network by adjusting the weight(s).

Title: Head pressure controller for air conditioning and refrigeration system
Inventor: SMITH GLENN W
IPC: G05D16/20
Filed: 1992-05-07
Granted: 1994-04-12
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention describes a method of controlling the head pressure in a refrigeration or air conditioning system in order to maintain the internal discharge pressure and discharge line pressure substantially equal.  The method consists of the steps of measuring the suction pressure of the working fluid, calculating the internal discharge pressure of the working fluid by multiplying the suction pressure by the internal pressure ratio of the compressor, measuring the discharge line pressure of the working fluid and then comparing the internal discharge pressure to the discharge line pressure.  If the difference between the internal discharge pressure and discharge line pressure is greater than some allowable tolerance, the capacity of the condenser is adjusted to equalize these two pressures.
